Control I/O Connector
Table 1 Control I/O Connector
Pin No. I/O Description
1 24 volt DC
2 Auxiliary output 2 inverted (open collector, max. 250 mA)
3 Auxiliary output 2 (open collector, max. 250 mA)
4 Auxiliary output 1 inverted (open collector, max. 250 mA)
5 Auxiliary output 1 (open collector, max. 250 mA)
6 Inject marker output (N.O. contact)
7 Inject marker output (N.C. contact)
8 Inject marker common (for N.O./N.C. contacts)
Note: Starting at the moment of injection, Inject marker contacts are
closed/openproducing a 1.0 sec. switch closure.
9 Inject marker output (TTL, active low)
10 Stop I/O (TTL, pulled up); output is low when the ProStar 400 AutoSampler ends
processing (READY); pull low input will stop processing (ProStar 400 goes to READY).
11 Spare (open collector)
12 Next vial input (active low, pulled up, TTL)
This input triggers a next vial to be processed when the ProStar 400 AutoSampler is in REMOTE
CONTROL mode.
13 Freeze (HOLD) input (active low, pulled up, TTL)
This input has the same function as the HOLD/CONT key (see Operation on page 17 ).
14 Next injection input (active low, pulled up, TTL)
This input triggers a next injection when the ProStar 400 AutoSampler is in REMOTE CONTROL
mode. It can also be used as a START input when the ProStar 400 is not in REMOTE CONTROL
mode.
15 Ground
16 Ground
NOTE: The duration of inputs 10, 12, and 14 must be at least 20 msec.
